You had quite a few underclassmen head to the North Star/Sioux Falls/Shattuck of the world. The Seniors I know of are Luc Bydal (Red River), and Colton Getzlaff (Bottineau) in the SJHL, and Max Vig (Century) went to Central Oklahoma of the NAHL.
There are probably ones that I'm forgetting, but those were the main seniors.
